AcuRite 13131 Alarm Clock - Manual (Page 2)

About the Atomic Clock
A clock is considered atomic if it has an accuracy of one second in a million years.
Consumer clocks are considered atomic if they attain this accuracy by receiving a
signal from an atomic clock. In North America, the National Institute of Standards
and Technologies operates an atomic clock in Colorado which transmits the time
codes via the the radio station WWVB. The signal is transmitted in a very low
frequency (60,000 Hz). The Acurite clock you have purchased includes a built-in
receiver which picks up the signal from the WWVB station. For the best possible
reception, place the main unit with the back side facing Colorado. NOTE: Due to solar
radiation in the atmosphere, the atomic clock signal is weaker during the day. Most
synchronization with the WWVB atomic clock signal happens at night when there is
less interference.
Basic Setup
After installing 3 AA Alkaline batteries, the year, month, date, time, time zone and
DST (daylight saving time) preferences must be set initially. After the initial manual
setting, the atomic clock will maintain it’s accuracy and adjust for DST automatically.
The alarm clock will automatically show the current time in Eastern Standard Time.

at least 3 feet (0.91 m) from other electronic
devices (i.e. TV’s, microwaves, computers,
etc.) that can interfere with wireless signals.
Check to make sure the batteries are installed
correctly. Use only fresh STANDARD “AA”
batteries, not generic or extra strength. Make
certain that the batteries are FRESH. If the
expiration date on your batteries is less than 6
years away, they may not contain a full charge
and can be weak.
